Total area of figure 1 = 408
Total area of figure 2 = 54
Total area of figure 3 = 392
Explanation:
Figure 1:
Area of rectangle 1 = l X b
= 16 X 15
= 240
Area of rectangle 2 = l X b
= 24 X (22-15)
= 24 X 7
= 168
Total area of the given figure = 240 + 168
= 408
Figure 2:
Area of rectangle = l X b
= 6 X 4
= 24
Area of triangle = area of 2 right angle triangle
height of the triangle = 10 - 4 = 6
base of the triangle = 5
Area of 2 right angle triangle = 2 X 1/2 X b X h
= 6 X 5
= 30
Total area of the figure = 24 + 30
= 54
Figure 3:
Area of rectangle = l X b
= 28 X 10
= 280
Area of right angle triangle = 1/2 X b X h
= 1/2 X (24-10) X (28-12)
= 1/2 X 14 X 16
= 112
Total area = 280 + 112
= 392
